The required electrodes and titration tips are inserted into the corresponding holes (NS 14.5, NS 7 etc.) of the
titration head. The TZ 1847 Rod Stirrer is also inserted into one of the bores. The electrical connection of the
stirrer is established with a cable attached to the stirrer to the stirrer socket on the back of the sample changer.
The stirring speed can be adjusted by software commands. The cables required for the operation of the titration
head are attached to the power supply of the titration head by means of the cable guides supplied (Fig. 17).

When using the TZ 3974 titration head, the TZ 1526 adapter is required for the use of a pH electrode with 12 mm
diameter. A conductivity electrode LF 413 fork can be used without adapter. If conductivity and pH value are
measured simultaneously, a micro pH electrode is required.
